Is saks.com Safe?

I had purchased a rather pricey Gucci sunglasses (GG3721S) , from SAKS ONLINE.And its been the biggest mistake of my life. I was absolutely shocked , upon getting my sunglasses ,it was clear that it had been tampered with but not by me. The Gucci sunglasses received without any warranty paperwork or a certificate of authenticity. Furthermore , it had been scratched twice , one in left lens and another on one arm . It is my belief it was in showroom not New one . I did the online customer support with SAKS.COM and that got me nowhere. They said its nothing they can do ,and one of their customer representative is telling me I can return the sunglasses and I will charged for all International Shipping fee ( that is cost a lot). And Here's the KICKER ( THERE IS NO GUARANTEE THEY TRUST TO REFUND MY MONEY OR EVEN ACCEPTED MY RETURN ) In good faith i gave Saks permission to charge my account in which they did, for a sunglasses , I had pre_ordered sight unseen, in good faith they should replace the DAMAGED SUNGLASSES they sent to me with apology sorry and additional compensation , or good corrective action to these horrible multiple mistakes. As customer , to be accused of something that is completely false is unacceptable, and I can assure you , as international customer , I will make sure to notify all international customers about your terrible return policy and unjust treatment of return. This is not a small Ticket Item , and effort it has taken on our side to address this ( a mistake on your company's behalf) is completely unacceptable.You have chosen to disregard the customer's words, ignored little details that clearly indicate the truth , and do not have the customer's best interest at heart . Absolutely terrible experience ,and i will never ever shop at SAKS again .
